JEE Main Physics Syllabus 2027

Which document this is: Syllabus for JEE (Main) – 2027, published by NTA. Physics has 20 units, and Unit 20 is Experimental Skills.

This is the latest one, published on NTA’s JEE Main site.

Last checked against the official document: 8 November 2026. We check it again every time NTA publishes a new one.

We checked the documents ourselves

We downloaded NTA’s own syllabus PDFs for 2023, 2025, 2026 and 2027 and compared them line by line.

The physics section of the 2025, 2026 and 2027 documents is 12,248 characters in each, and all three give the same checksum. They are the same text. The only difference anywhere in the 2027 file is the year printed on the cover.

The real change happened between 2023 and 2025. That is the revision everyone calls the 2024 revision, and it cut the physics section from 13,053 characters to 12,248.

Is dispersive power in the JEE Main syllabus?

No — and it has never been named in it. The words “dispersive power” do not appear in the JEE Main physics syllabus of 2023, 2025, 2026 or 2027. What the 2023 document did carry was the line “Deviation and Dispersion of light by a prism”. That line was removed. Unit 16 today says only “refraction of light through a prism”. So dispersive power and angular dispersion cannot be asked.

Is limit of resolution or resolving power in the syllabus?

No. NTA’s own wording was “Resolving power of microscopes and astronomical telescopes”, and it sat in the 2023 document. It is not in the 2025, 2026 or 2027 document. The phrase “limit of resolution” has never appeared in any of them.

Are the microscope and telescope deleted?

No. This is the one most students get wrong. The 2027 syllabus still carries “microscope and astronomical telescope (reflecting and refracting) and their magnifying powers”, word for word as it stood in 2023. Only their resolving power was removed. Magnifying power is still fully askable.

Is Reynolds number in the JEE Main syllabus?

No. It stood in the 2023 document under Properties of Solids and Liquids and is absent from 2025 onward. Newton’s law of cooling went with it. Viscosity, Stoke’s law, terminal velocity and Bernoulli’s principle all stay.

Is radioactivity or half life in the JEE Main syllabus?

No. Unit 18 keeps mass defect, binding energy per nucleon, nuclear fission and fusion. Radioactivity, the radioactive decay law, half life, isotopes and isobars are all gone. Many students still revise this chapter in full and lose a week on it.

Are vectors in the JEE Main syllabus?

No for JEE Main. Yes for NEET(UG). The word “vector” does not appear even once in the JEE Main 2027 physics syllabus. The 2023 document had vector addition, scalar and vector products and resolution of a vector. NEET(UG) Unit 2 still lists all of them. This is the one real difference between the two exams.

Are capacitors deleted from JEE Main physics?

No. Capacitors and capacitance appear eight times in the 2027 physics text, in Unit 11, including combination in series and parallel, parallel plate capacitors with and without a dielectric, and energy stored. At least one well known coaching page lists capacitors as excluded. That is wrong.

Is the prism chapter deleted?

Only partly. Dispersion by a prism is gone from Optics. But “refraction of light through a prism” is still in Unit 16, and Unit 20 Experimental Skills still carries “the plot of the angle of deviation vs angle of incidence for a triangular prism”. So deviation survives, inside the experiments.

Has anything changed in the JEE Main 2027 physics syllabus?

Nothing at all. We compared NTA’s own PDFs. The physics section of the 2025, 2026 and 2027 documents is 12,248 characters in each, and all three produce the same checksum. The 2027 file is the 2026 file with the year changed on the cover. If you prepared from the 2026 syllabus, you are already on the 2027 syllabus.

Was there a separate JEE Main 2024 syllabus?

No separate document exists. NTA’s own documents page lists a single PDF under the heading “Syllabus for JEE (Main) 2025, 2024”, exactly as the current row reads “Syllabus 2027, 2026”. NTA puts two years on one document.

A syllabus tells you what can be asked. It does not tell you what you can answer. Only a timed paper does that.(सिलेबस यह बताता है कि क्या पूछा जा सकता है। यह नहीं बताता कि आप क्या हल कर सकते हैं। यह सिर्फ़ टाइम लगाकर दिया गया पेपर बताता है।)

Dhurandhar has three timed papers for every chapter of this syllabus, each with a target score, an answer key and a hint for every question. Read a chapter, then sit its paper the same week.(धुरंधर में इस सिलेबस के हर चैप्टर के तीन टाइम्ड पेपर हैं — टारगेट स्कोर, आंसर की, और हर सवाल का हिंट। एक चैप्टर पढ़िए, और उसी हफ़्ते उसका पेपर दीजिए।)

हर सवाल पर वार करो,
धुरंधर बनकर JEE पार करो!
